Experimental Investigation of Wash Fluid Preheating on the effectiveness of online Compressor Washing in a Suction Tunnel Compressor Cascade

Online compressor washing is a promising method of preventing/ recovering the effects fouling on blades. However, proper strategies need to be implemented for online effective since it conducted when engine in operation. This study presents an experimental investigation wash fluid preheating effectiveness suction wind tunnel cascade. Crude oil was uniformly applied cascade blade surfaces using roller brush, and carborundum particles were ingested into create accelerated fouled Demineralized water preheated 500C heat coil provided tank. Washing blades single flat fan nozzle, where non demineralized used separately When washed with non-preheated compared, observed that there little or no difference terms total pressure loss coefficient exit flow angle. cases significant
